【 摘 要 】

We report on magnetization measurements of RbFeBr3 single crystals. At ambient pressure, the field-temperature phase diagram has been determined up to 70 kOe for Hc. It is found that the application of magnetic field for Hc expands the low temperature phase with the triangular spin structure (T N2) and suppresses the partially disordered phase (TN2n1). When hydrostatic pressure is applied under 100 Oe for Hc, the magnetization anomaly related to TN1shifts to lower temperatures and is no more detectable at P ≥ 1.0 GPa.
